my sons drr50 smoke my buddies yfz450 today in a 300ft drag by about 200ft. it was comical my buddy was bragging about his yfz (which was very quick) how it would smoke anything stock for stock. so jokingly i told him i would run him 300ft on my sons drr50. we lined up & leter rip. the yfz blew its engine about 75ft into it. i just laugh at him when i went by him on the 50. bad thing is he just had the cam mod, pipe, 13:1 piston, air filter, & jets done not even a week ago. it was a bad way to win but hey winning is winning lol

 

do you know what happened to his motor yet?.........or is it too soon to tell?

 

I wonder if it was the ol' Selector Circlip Situation.

 

What went wrong with selectors YFZ????

 

PLEASE let me know what you find.

selector

Doesn't sound like your dealer, Erik. [img]i/expressions/face-icon-small-sad.gif[/img]
